Answer:

ans: 4

Step-by-step explanation:

corresponding sides are proportional since given triangle are similar triangle, I.e

(4/5.5) = { (2x+8)/(6x-2)}

8/11 = ( x+ 4 ) / ( 3x - 1 )

8( 3x - 1 )= 11( x + 4 )

24x - 8 = 11x + 44

13x = 52

x = 4

Answer:

The large sample n = 1713.96

Step-by-step explanation:

<u>Explanation</u>:-

given the population proportion was estimated to be 0.22

population proportion (P) = 0.22

The 95 % level of significance = 1.96≅ 2

The margin of  error = 0.02

The formula of margin error

                                   \frac{2\sqrt{p(1-p)} }{\sqrt{n} } = 0.02    …  ( i )

Substitute 'p' values in equation (1)

\frac{2\sqrt{0.22(1-0.22)} }{\sqrt{n} } = 0.02

cross multiplication and simplification, we get

2X0.414= 0.02 \sqrt{n}

\frac{2X0.414}{0.02} = \sqrt{n}

41.4 = \sqrt{n}

squaring on both sides, we get

the large sample n = 1713.96

Leokris [45]

Answer:
